[UWP] XREnabled is true even if no headset is connected. Using flat mode is impossible

1. What happened
A UWP project iwth Virtual Reality Supported checked will try to start the VR view even if a headset is not connected. If this option is checked, it's impossible to use the app in flat mode because Unity tries to activate the VR mode.
When the application is started, the mixed reality portal is started but no headset is connected.
You can take a look at XRSettings to see that enabled is true, isDeviceActive is true, etc.

This problem happens in the editor AND the player.

2. How we can reproduce it using the example you attached
- Open the only scene of the project
- Switch to Windows Universal Platform
- DO NOT connect any headset
- Press play

The Mixed Reality portal will open, the camera's transform is overrided by the SDK and some error messages will pop in the console.

In some cases, the OpenVR is also started, it happens when you uncheck VR Supported and press play.

Hi Yannick,

Thanks a lot for reporting the issue.

Could you clarify more specifically what happened?
The issue doesn't seem to reproduce for us.
Are your project's XR settings disabled?
The projects is quite empty. I assume you've attached up-to-date copy of it?

RE: (Case 1007117) [UWP] XREnabled is true even if no headset isconnected. Using flat mode is impossible

Hello,

First you’ve to install SteamVR + Windows Mixed Reality for SteamVR. My PC uses the latest Windows 10 stable version aka Fall Creator Update. We’re talking about Windows Mixed Reality and the UWP target.

With recent versions of Unity (2017.3.1pX + 2018.1) I’ve this issue. In depth, sometime I start the project with a VR preview. It uses the Mixed Reality Portal. If I uncheck the XR Settings Enabled to try without VR, SteamVR is started. I don’t know how it is possible because SteamVR can’t be used with UWP.

Also, when it happens, XRSettings.enabled is true, that makes no sense because the checkbox is unchecked.

I hope it can help,

Regards,

Hi,

I've tested a bit and the Steam VR didn't seem to launch.
Should Steam be enable before launching the project?

Hi,

Could you try the steps mentioned with an empty project rather than your original project?
The issue doesn't seem to reproduce on our end.
